Hello mate
No, if you bridge sidelight's positive wire with positive on DRLs(assuming you have DRL which you would on Bi-xenon headlights, and have P21W LED cree leds fitted as well as DRLs) then all you do is changing coding via VCDS in [09] from Bi-xenon with halogen drl lights to Bi-xenon with led drl light and that's it.
No errors, no resistors, and leds will also dim with main beam on as they to on oem led headlights.
